IMPROVEMENT IN HEIVIMING AND BINDING ATTACHMENTS FORSEWING-MACHINES.

Specification forming part of Letters Patent No. 127,158, dated May 28,1872 antedated May 18, 1872.

SPECIFICATION.

Nature of Invention.

This invention relates to sewing-machine attachments; and consists inthe combination and arrangement of my duplex hemmer with a binder,substantially as hereinafter described.

General Description.

In the drawing, Figure 1 is a perspective view of my arrangement in use;Fig. 2, a perspective view of the device from the rear 3 Fig. 3, an endelevation of the end next the presserfoot, in Fig. 1, showing the clothand binding in section; Fig. 4, a detached end elevation of theduplex-folder and binding-guide Fig. 5,, a sectional view of a piece ofthe goods after having been folded and bound by my device; Fig. 6, aperspective view of the guide substituted for the duplex-folder when itis desired to bind only.

Ais the base-piece, secured to the cloth-plate or table of the machineby a thumb-screw, B, passing through the slot 1) between the arms a a,and screwing into the cloth-plate, the slot 1) allowing the adjustmentof the device with relation to the presser-foot, needle, 8:0. The arms aa are bent over or otherwise formed, so as to receive and form ways orguides for the arms 0 c of the binding-guide G, which projects forwardpreferably under the base-piece A, beyond the latter, and is providedwith a guide, 0, through which the under edge of the binding passes onits way to the needle, as hereinafter described. A socket, c of suitableform, is also provided, into which the bearing e of the folder E orguide E is inserted. The folder E is an invention of mine claimedelsewhere, and in this case consists of the folding arms e e guide c andslot 6 provided with the tongue or bearing e, before mentioned. A

guide, a projects from the front of the basepiece A, and is curvedforward the whole or a portion of its length, as at a. E is a simpleguide, substituted for the folder E when it is desired to bind withouthemming.

The operation is as follows: The base-piece A having been secured to thecloth-plate or table, by means of the thumb-screw B, in the properrelative position to the presser-foot and needle, the folder E is thenadjusted in its socket a so as to leave just the necessary space (asshown in Figs. 1, 2, 3, and 4) between its outer convex surface and theinner concave surface of the guide a afor the binding G to pass freelybetween, but without allowing it any play or the necessity'of itsbending transversely in its progress. The guide 0 is next adjusted tothe proper distance from the guide a so that itwill receive and guidethe under edge of the binding G, (as shown in Fig. 3.) I design to use acombined presserfoot and edge-stitching guide in connection with thedevice, so that the upper edge of the binding will be controlled andguided by it similar to the way in which the guide 0 controls the loweredge. All things being ready, the edges of the two pieces of cloth, I J,to be united and bound, are passed throughthe arms 6 e of the folder E,which fold the edges or selvage inward together and between the cloth,producing the duplex hem, while at the same time the binding G is fed inbetween the outer convex surface of the folder E and the inner concavesurface of the guide a a.*, by which means it is bent and guided aroundthe 11cm, the under edge passing through the guide 0, as before stated,while the upper edge passes under the ed ge-guide or presser-foot. Thehem and binding being thus folded into place and prepared for the actionof the needle, upon reaching the latter the several parts are securelysewed together. The guide 0 controls the extent to which the bindinglaps over the hem on either side, by being adjusted to or from theguiding surface a and prevents its escaping or varying in position onits way to the needle. By having several folders of different form, thewidth, number of folds, &c., of the hem maybevaried at pleasure bysimply removing the one in use and substituting another adapted to givethe desiredresult. Where it is desired to bind only, the folder isremoved and a plain guide, E, is substituted, when the construction andoperation of the device is substantially the same as that patented by meJuly 4, D. 1871, and numbered 116,570.

The advantages of thus combining and arranging a duplex hemmer anda'binder in one attachment for sewing-machines are obvious. The cost oftwo separate attachments is avoided, and convenience and economy ofspace attained. Heretofore the hem has first been formed and sewedtogether, and then the binding applied and sewed on, necessitating thepassing of the goods under the needle at least twice, and consuming muchtime and effort; whereas, by my invention the duplex hem is formed andthe binding folded over it in the proper manner automatically, and at asingle operation, and the whole is securely sewed by passing the clothunder the needle once-a result which I believe myself to be the first toattain. The facility with which it can be converted into a simplehinder, or the form of the hem varied, 850., by simply changing theguide or folder, is another example of its merits. Its simplicity andease of adjustment allow the action to be controlled with the greatestdelicacy. The economy of time and labor, and

the convenience and perfection attained, indorse the invention as ofimportance and value.

What I claim as my invention, and desire to secure by Letters Patent, is

' 1. The combination, in a sewing-machine attachment, of a duplex hemmerand binder, arranged so as to form the hems and fold the binding oversaid hems at one operation, for the purpose described.

2. The folder E, formed as shown at 6 and provided with the folding arms0 c and guide 0 when all constructed as described and shown, andcombined with the base-piece A.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
